Scabies presents as an intensely pruritic rash that predominantly involves hairless and thin skin such as web spaces of the hands and skin creases. Sensitization to mite products is responsible for the itch and therefore symptom onset is usually delayed by weeks in the first infection. Secondary bacterial infection with Staphylococcus aureus and Streptococcus pyogenes is responsible for significant morbidity. Crusted scabies, the most severe form of scabies, presents as a hyperkeratotic rash. Lesions are loaded with mites and such patients are highly infectious. Direct skin-to-skin contact is the most important mode of transmission. Parasitological diagnosis is difficult and therefore clinical diagnosis is usually relied upon, although new diagnostic methods are under development. The most commonly used treatment of choice is topical permethrin cream applied to the whole body. Ivermectin, administered orally, is increasingly being used, including for mass drug administration.

"This chapter is divided into three sections. The first provides the reader with a historical perspective of Australian Aboriginal and Torres Strait islander peoples, the impact of colonisation and contemporary access to mental health care. The second section is written from a remote rural mental health nurse perspective, providing insight into some of the concerns and challenges of working in often far distant places, away from acute care services, to provide mental health care to Indigenous people within Australia. The last section comes from our colleagues in New Zealand, exploring the bi-cultural nature of mental health care in that country. This section offers insights into how care can be provided within a culturally safe and inclusive manner. " -- taken from the introduction to the chapter.

Chemotherapy-induced nausea and vomiting (CINV) remains an important issue for patients receiving chemotherapy despite guideline-consistent antiemetic therapy. Trials using delta-9-tetrahydrocannabinol-rich (THC) products demonstrate limited antiemetic effect, significant adverse events and flawed study design. Trials using cannabidiol-rich (CBD) products demonstrate improved efficacy and psychological adverse event profile. No definitive trials have been conducted to support the use of cannabinoids for this indication, nor has the potential economic impact of incorporating such regimens into the Australian healthcare system been established. CannabisCINV aims to assess the efficacy, safety and cost-effectiveness of adding TN-TC11M, an oral THC/CBD extract to guideline-consistent antiemetics in the secondary prevention of CINV. The current multicentre, 1:1 randomised cross-over, placebo-controlled pilot study will recruit 80 adult patients with any malignancy, experiencing CINV during moderate to highly emetogenic chemotherapy despite guideline-consistent antiemetics. Patients receive oral TN-TC11M (THC 2.5mg/CBD 2.5 mg) capsules or placebo capsules three times a day on day -1 to day 5 of cycle A of chemotherapy, followed by the alternative drug regimen during cycle B of chemotherapy and the preferred drug regimen during cycle C. The primary endpoint is the proportion of subjects attaining a complete response to CINV. Secondary and tertiary endpoints include regimen tolerability, impact on quality of life and health system resource use. The primary assessment tool is patient diaries, which are filled from day -1 to day 5. A subsequent randomised placebo-controlled parallel phase III trial will recruit a further 250 patients. The protocol was approved by ethics review committees for all participating sites. Results will be disseminated in peer-reviewed journals and at scientific conferences. Tilray. 2.0, 9 June 2017.

BACKGROUND: A cornerstone of Australia's ability to control COVID-19 has been effective border control with an extensive supervised quarantine programme. However, a rapid recrudescence of COVID-19 was observed in the state of Victoria in June, 2020. We aim to describe the genomic findings that located the source of this second wave and show the role of genomic epidemiology in the successful elimination of COVID-19 for a second time in Australia. METHODS: In this observational, genomic epidemiological study, we did genomic sequencing of all laboratory-confirmed cases of COVID-19 diagnosed in Victoria, Australia between Jan 25, 2020, and Jan 31, 2021. We did phylogenetic analyses, genomic cluster discovery, and integrated results with epidemiological data (detailed information on demographics, risk factors, and exposure) collected via interview by the Victorian Government Department of Health. Genomic transmission networks were used to group multiple genomic clusters when epidemiological and genomic data suggested they arose from a single importation event and diversified within Victoria. To identify transmission of emergent lineages between Victoria and other states or territories in Australia, all publicly available SARS-CoV-2 sequences uploaded before Feb 11, 2021, were obtained from the national sequence sharing programme AusTrakka, and epidemiological data were obtained from the submitting laboratories. We did phylodynamic analyses to estimate the growth rate, doubling time, and number of days from the first local infection to the collection of the first sequenced genome for the dominant local cluster, and compared our growth estimates to previously published estimates from a similar growth phase of lineage B.1.1.7 (also known as the Alpha variant) in the UK. FINDINGS: Between Jan 25, 2020, and Jan 31, 2021, there were 20 451 laboratory-confirmed cases of COVID-19 in Victoria, Australia, of which 15 431 were submitted for sequencing, and 11 711 met all quality control metrics and were included in our analysis. We identified 595 genomic clusters, with a median of five cases per cluster (IQR 2-11). Overall, samples from 11 503 (98·2%) of 11 711 cases clustered with another sample in Victoria, either within a genomic cluster or transmission network. Genomic analysis revealed that 10 426 cases, including 10 416 (98·4%) of 10 584 locally acquired cases, diagnosed during the second wave (between June and October, 2020) were derived from a single incursion from hotel quarantine, with the outbreak lineage (transmission network G, lineage D.2) rapidly detected in other Australian states and territories. Phylodynamic analyses indicated that the epidemic growth rate of the outbreak lineage in Victoria during the initial growth phase (samples collected between June 4 and July 9, 2020; 47·4 putative transmission events, per branch, per year [1/years; 95% credible interval 26·0-85·0]), was similar to that of other reported variants, such as B.1.1.7 in the UK (mean approximately 71·5 1/years). Strict interventions were implemented, and the outbreak lineage has not been detected in Australia since Oct 29, 2020. Subsequent cases represented independent international or interstate introductions, with limited local spread. INTERPRETATION: Our study highlights how rapid escalation of clonal outbreaks can occur from a single incursion. However, strict quarantine measures and decisive public health responses to emergent cases are effective, even with high epidemic growth rates. Real-time genomic surveillance can alter the way in which public health agencies view and respond to COVID-19 outbreaks.

Smokeless tobacco is the term used to describe a range of products found worldwide which individuals use to extract nicotine, but without smoking. Ways of achieving this include chewing, sniffing and placing in areas of the body where tissues are sufficiently thin for absorption to take place such as the oral mucosa or postauricular skin. In Central Australia, Aboriginal groups across a wide area have chewed wild tobacco plants, commonly known as Pituri, for countless generations. As well as inducing a sense of well-being, the habit has strong cultural significance. While some smokeless tobacco products used outside Australia are known to have a detrimental effect on oral health, particularly malignant change, little is known about Pituri. To date, reports of adverse oral outcomes have been elusive. Most Pituri research seems to have focussed on obstetric issues, arguably unexpected as the tobacco seems to be in contact with the mouth for longer than any other body tissues. The following report describes a lesion on the anterior buccal mucosa resulting from prolonged Pituri use. The relevant literature is reviewed. A clinical and ethical management dilemma arises between respecting the associated cultural issues and ignoring an apparent pathological entity. © 2022 Australian Dental Association.

The Operations Manager and a Technical Officer of Medical Entomology (ME) went to Tennant Creek on 2-6 February 2009. The purpose of the ME visit was to introduce the local Environmental Health Officer to the Tennant Creek mosquito survey and control program, to carry out house to house receptacle surveys, as a follow up from the Aedes aegypti incursion in 2004, and to carry out a general inspection of potential mosquito breeding sites after recent significant rain (348.2mm TCK/Jan) and flooding in the Barkly region.
